Abstract
The instant invention is directed to a mixing head for mixing reactants preferably for the production of foam. The mixing head is characterized as having a housing in which an ejector piston is guided, the guide bore of said piston being crossed by a guide bore for a restrictor slide which has a passage for the ejector piston, an outlet element being situated immediately subjacent to said passage, and, in the most preferable embodiment, the restrictor slide and ejector piston being connected to a control device.
